摘    要:研究了2,4—D,NAA,PP333以及糖对怀山药微型块茎诱导形成的影响。结果表明:2,4—D,NAA单独使用时,诱导微型块茎形成的合适浓度均为0.5mg/L,形成的微型块茎较多且较大;2,4.D与NAA组合中,NAA0.5mg/L 2,4—D0.5mg/L所诱导的微型块茎较多且较大;NAA为0.5mg/L时,与PP333 0.1mg/L的组合所诱导的微型块茎较多且较大,微型块茎形成率高达100%;蔗糖较白砂糖诱导形成的微型块茎多且大。

关 键 词:怀山药  微型块茎  NAA  2  4-D  PP333

Abstract:This paper mainly deal with the effect of 2,4-D,NAA,PP333 and carbohydrate on the induction of bubils of Dioscorea opposita Thunb. The results show the more suitable concentration of NAA or 2,4-D was 0.5 mg XL, which could single induct more and bigger bubils; Among the combinations of growth regulatiors, NAA 0.5 mg/L + 2,4-D 0.5 mg/L can induct more and bigger bubils. When NAA being 0.5 mg/L,PP333 0.1 mg/L could induct more and bigger bubils. The inducting percent of bubils was 100% .Comparing sucrose and sugar, we finded that sucrose could induct more and bigger bubils than sugar.
Keywords:Dioscorea opposita Thunb.  Bubil  NAA  2  4-D  PP333  Carbohydrate
